What is the difference between Calabash-ios and Calabash-cucumber?
calabash-ios and calabash-cucumber both refer to the same gem, so there is no difference.
https://github.com/calabash/calabash-ios
the reason the gem is called calabash-cucumber is historical - in the beginning there was no calabash-android gem.
i believe the plan is change the gem name to calabash-ios in version 1.0.
